There are laws for the physical realm. There are also money laws.
One of them is have a plan! Be able to answer when you are asked about it, but beware: not everyone should know your plan! I would say your friends can know your plan and the ones you love should know your plan. I call a friend based on the old proverb “a friend in need is a friend indeed”. Other people have other definitions, which I do not adhere to; they say for example their friends are the ones they party with, or the ones they talk with.
Another one is a warning that who you listen to like him you become.
Also think I also have evidence for these: one should not lend 100% of what he is asked; don’t refuse someone asking you for money for his first home but give him as little as possible; when one has money others try to get it; it’s better to control assets than to own assets; when some business of yours is too good you’ll start having competition; when you have an idea you’ll lead no matter how much competition you’ll have except if you fall tired; copyright, invention and innovation are strong tools to create wealth and many don’t see it; he who is faithful with little will be faithful with a lot, and he who is not faithful with little can’t develop the character to be faithful with a lot.
